1. A method for automatically controlling by automatic control circuitry a therapeutic ultrasound transducer for ultrasonically treating tissue and comprising the steps of:

  • (a) providing means for inputting tissue treatment parameters into automatic control circuitry operatively connected to a therapeutic ultrasound transducer;

    (b) upon tissue treatment parameters being entered, automatically calculating by said control circuitry an ultrasound treatment dosage based on input tissue treatment parameters said treatment dosage including at least two dosage factors which are mathematically related to said dosage;

    (c) upon no tissue treatment parameters being entered, automatically calculating by said control circuitry an ultrasound treatment dosage based on selected default tissue treatment parameters;

    (d) automatically controlling said ultrasound transducer by said control circuitry to maintain the calculated ultrasound treatment dosage;

    (e) manually varying a first of said dosage factors; and

    (f) automatically varying a second of said dosage factors to compensate for variation of the first dosage factor to thereby maintain the previously calculated dosage.
